• file://

Direct repository access to local or network drive.

• http:// Access via WebDAV protocol to Subversion-aware Apache server.

• https:// Same as http://, but with SSL encryption.

• svn:// Unauthenticated TCP/IP access via custom protocol to an svnserve server.

• svn+ssh:// Authenticated, encrypted TCP/IP access via custom protocol to an svn server.

Architecture Access URLs

• file://hostname/path/to/repos

On local machines the hostname part must either be absent or localhost.

• This results in a path like this one:

file:///path/to/repos

• On Windows you have to specify the drive where to find the repository:

file:///X:/path/to/repos

trunk/tags/branches on root; each module will be tagged separately

•checkout of all modules is possible•commits can span multiple modules•tags can not span multiple modules in single commit (workaround by 3rd party tools)
